@sinbad the inner doors in this place are surprisingly effective actually. We at least don't need draught excluders I don't think. Would be useless on the main door too - the bottom is the only bit that's snug haha.
You had no central heating though? 😬
Presumably the fireplaces were all at least still active? Some of ours are, but I've not yet dared to try starting an indoor fire. Only ever had electric before and if you'd ever seen one of my firepits, you'd keep me away from the matches 😆
